Over 50%, for sure, but I doubt that will give you mold problems. The humidity is higher than that all summer here, and mold isn’t really a problem.
I think if you kept the room at 60% you will find that it’s okay for the bird, and okay as far as mold goes.
I’m running 2 humidifiers, but I struggle to get the humidity over 45%. The winter air is dry, and my heat, a forced hot water system, doesn’t add any humidity to the air. I wish I had one of the old steam systems. Those were great for getting humidity into the room.
